One of the most environmentally friendly methods to treat wastewater, especially synthetic dyes, is production activated carbon from agricultural waste. Tamarind seeds were transformed negative-value waste into in order study removal dyes. The particular agro was soaked ZnCl2 for chemical activation increase its surface area and enhance porosity. Physical tamarind done by carbonization process ...

Cellulosic materials like cotton and linen are excellent textile substrates for dyeing with reactive direct dyes. Due to their cellulosic nature, exhibit good affinity towards This is the reason washing rubbing fastness. Chitosan a bio-based polymer gained by deacetylation of chitin. In contrast cellulose, chitosan exhibits also amino functional groups. The purpose this paper evaluate if based ...

When the textile industry wastewater volume and considering composition appears to be one of most environmentally hazardous industries. Due basic properties dyeing wastewater, additional precaution are required besides conventional treatment remove color. The approach is color break down chromophores double bonds that make up by oxidative means. In this study, treatability containing Reactive Y...

The aim of this research is to develop new mordants and a wide range of colors for natural dyeing of silk. In this study, two new erbium(ΙΙΙ) complexes, [Er(AO)(H2O)7](OAc)3 and [Er(AMH)(H2O)6](OAc)3 (AO = acridine orange, AMH = azomethine-H, and OAc = acetate anion), were synthesized, characterized and used as a mordant for the natural dyeing of silk yarns with an aqueous extract of green waln...

The objective of this work was to determine the optimal conditions for electrooxidation treatment in order decolourise effluents that contain reactive dyes. According results, when Na2SO4 is used as an electrolyte, decolouration reactions follow first-order kinetics. However, NaCl present effluent, kinetics stabilised after applying a minimal electric current value. models obtained from results...

Textile dyeing is considered to be one of the major industrial sources of high rates of organic and aromatic compounds. Conversely, these compounds have become a significant environmental problem. Many methods have been investigated for color removal from dye-containing wastewater. In this research, the efficiency of the electrocoagulation (EC) process with aluminum electrodes in the removal of...

Background & objectives: Dyes are structurally complex materials, which enter into the environment due to discharging of textiles effluent from dyeing and printing processes. Reactive Blue 52 dye is used widely in the textile industry. Therefore, we investigated the efficiency of the filamentous Alga as natural adsorbent in the removal of Reactive Blue 52 dye from textile wastewater. Methods: ...

Sustainable chemistry is a relatively new field that aims to achieve both economic and environmental goals simultaneously. This paper discusses cleaner more sustainable method for dyeing cotton fabric using Direct Violet 09 Reactive 05 dye. It has been noticed good color characteristics were obtained when was dyed with 35 mL of microwave-treated dye solution 7 pH 2 g Aluminum sulfate 30 min at ...
